• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chau) OR (ho chu)) tinh - hanh ((trung cua) OR (trung tuan)) nhung cong vang toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chau) OR (ho chu)) tinh - hanh ((trung cua) or (trung tuan)) nhung cong vang toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chau) OR (ho chu)) tinh - hanh ((trung cua) or (trung tuan)) nhung cong vang toan cao*.
